Additional information

Expression and regulation

  • Regulation: repressed by glucose (CcpA) , carbon catabolite repression, induction by fructose
  • Regulatory mechanism: CcpA: transcription repression, catabolite repression: transcription repression by CcpA, transcription activator LevR is less active in the presence of glucose; induction: transcription activation by LevR
